Off the strip, the shopping center at the NE corner of Jones Blvd. and Spring Mountain Road has three pretty good choices--Asian BBQ & Noodles for noodles, China Mama for Shanghai style, and H K Star for Hong Kong style. Near there on Spring Mountain is K J Kitchen, which also has a better and much pricier branch in the Rio. In Henderson, East Ocean on Eastern Ave. is quite good.

I think the food is higher in quality at the Rio location, closer in quality to what you can get in Los Angeles, BUT it's so much more expensive that it's not worth it. Personally I'm not going back to the Rio branch for that reason.
